Elevator, escalator and moving walk systems are among the most complicated systems in any urban environment, no less so than on the #WiseCampus in which many large research universities have 100 to 1000 elevators to safely and economically operate, service and continuously commission. These systems are regulated heavily at state and local levels of government and have oversight from volunteers that are passionate about their work.
These “movement systems” are absorbed into the Internet of Things transformation. Lately we have tried to keep pace with the expansion of requirements to include software integration professionals to coordinate the interoperability of elevators, lifts and escalators with building automation systems for fire safety, indoor air quality and disaster management. Much of work requires understanding of the local adaptations of national building codes.
Some university elevator O&M units use a combination of in-house, manufacturer and standing order contractors to accomplish their safety and sustainability objectives.
In the United States the American Society of Mechanical Engineers is the dominant standards developer of elevator and escalator system best practice titles; its breakdown of technical committees listed in the link below:
As always, we encourage facility managers, elevator shop personnel to participate directly in the ASME Codes & Standards development process. For example, it would be relatively easy for our colleagues in the Phoenix, Arizona region to attend one or more of the technical committee meetings; ideally with operating data and a solid proposal for improving the A17 suite.
All ASME standards are on the agenda of our Mechanical, Pathway and Elevator & Lift colloquia. See our CALENDAR for the next online teleconferences; open to everyone. Use the login credentials at the upper right of our home page.

Classical architects, drawing from ancient Greek and Roman traditions (as codified by Vitruvius), regarded building entrances as the primary expression of venustas (beauty), alongside strength and utility. Entrances served as grand thresholds, symbolizing transition from the profane exterior to the ordered interior.They achieved beauty through harmonious proportion, symmetry, and the golden ratio, ensuring visual delight.
Porticos with elegant columns (Doric, Ionic, or Corinthian), entablatures, and pediments framed doorways, creating majestic first impressions. These elements conveyed prestige, invited reverence, and embodied ideal order, making the entrance the façade’s focal point of timeless elegance and civic or domestic dignity.
We present improvements that are possible on the University of Michigan Ann Arbor campus. We acknowledge that interior design and functionality may have to change.

Standards of beauty for building entrances in architecture emphasize creating a welcoming, harmonious, and memorable first impression. Core principles draw from timeless design tenets like proportion, scale, balance, and emphasis, ensuring the entrance feels appropriately sized relative to the overall structure and surroundings—neither overwhelming nor insignificant.
A beautiful entrance often features symmetry or thoughtful asymmetry for visual harmony, grand yet human-scaled elements like arches, columns, porticos, or recessed doorways that add depth and shelter. Materials matter: high-quality doors (glass for transparency, wood for warmth, or metal for modernity) combined with textures that complement the building’s style create tactile and visual appeal.
Ultimately, beauty arises from blending functionality (accessibility, security, weather protection) with emotional impact: an entrance that feels inviting, ordered, and reflective of the building’s purpose or cultural context.

Means of egress rules, primarily from the International Building Code (IBC) and NFPA 101, dictate the number and sizes of exit doors to ensure safe evacuation.
Number of exits: Most spaces require at least two exits when the occupant load exceeds 49 (for many occupancies like assembly, business, or mercantile). Loads of 501–1,000 need three exits, and over 1,000 require four or more. Single exits are allowed for low-occupant areas (often ≤49 people) with limited travel distances.
Sizes: Exit doors must provide a minimum clear opening width of 32 inches (813 mm). Required total egress width is calculated from occupant load (typically 0.2 inches per person for nonsprinklered buildings or 0.15 inches for sprinklered), distributed across exits. Doors swing in the egress direction for loads over 50 and must remain operable without keys or special effort.
These ensure adequate capacity and redundancy during emergencies. We treat security standards separately. See our CALENDAR

Today we break down consultations on titles relevant to the technology and management of the real assets of education communities in the United States specifically; but with sensitivity to the global education markets where thousands of like-minded organizations also provide credentialing, instruction, research, a home for local fine arts and sport.
“Even apart from the instability due to speculation, there is the instability due to the characteristic of human nature that a large proportion of our positive activities depend on spontaneous optimism rather than on a mathematical expectation, whether moral or hedonistic or economic. Most, probably, of our decisions to do something positive, the full consequences of which will be drawn out over many days to come, can only be taken as the result of animal spirits — a spontaneous urge to action rather than inaction, and not as the outcome of a weighted average of quantitative benefits multiplied by quantitative probabilities. Enterprise only pretends to itself to be mainly actuated by the statements in its own prospectus, however candid and sincere that prospectus may be. Only a little more than an expedition to the South Pole is it based on an exact calculation of benefits to come. Thus if the animal spirits are dimmed and the spontaneous optimism falters, leaving us to depend on nothing but a mathematical expectation, enterprise will fade and die; — though fears of loss may have a basis no more reasonable than hopes of profit had before.”
Extended Versions Certain standards are required to be read in tandem with another standard, which is known as a reference (or parent) document. The extended version (EXV) of an IEC Standard facilitates the user to be able to consult both IEC standards simultaneously in a single, easy-to-use document.
A partial list of projects with which we have been engaged as an active participant; starting with the original University of Michigan enterprise in the late 1990’s and related collaborations with IEEE and others: (In BOLD font we identify committees with open consultations requiring a response from US stakeholders before next month’s Hello World! colloquium)
IEC/TC 8, et al System aspects of electrical energy supply
We collaborate with the appropriate ANSI US TAG; or others elsewhere in academia. We have begun tracking ITU titles with special attention to ITU Radio Communication Sector.

We have collaborations with Rijksuniversiteit Groningen, Sapienza – Università di Roma, Universität Zürich, Universität Potsdam, Université de Toulouse. Universidade Federal de Itajubá, University of Windsor, the University of Alberta, to name a few — most of whom collaborate with us on electrotechnology issues. Standards Michigan and its 50-state affiliates are (obviously) domiciled in the United States. However, and for most issues, we defer to the International Standards expertise at the American National Standards Institute
* A “Hello, World!” program generally is a computer program that outputs or displays the message “Hello, World!”. Such a program is very simple in most programming languages (such as Python and Javascript) and is often used to illustrate the basic syntax of a programming language. It is often the first program written by people learning to code. It can also be used as a sanity test to make sure that a computer language is correctly installed, and that the operator understands how to use it.
A standard is a common solution to a recurring problem. The purpose of standards is to create uniform and transparent procedures that we can agree on. It is in everyone’s interest to increase quality, avoid misunderstandings and avoid reinventing the wheel every time.
Standards pave the way for more efficient and resource-efficient production. They also make it easier to procure and sign contracts, as they ensure that buyers and suppliers speak the same language.
